I've looked at many of the posts and tried the solutions, but I none have helped so I am writing in hopes that someone will be able to give me the steps.
I have a Toshiba Tecra that has a Nvidia quadro nvs 150m graphic card. I have it in my docking station, a Toshiba Dynadock and have 2 ViewSonic VG2227wm monitors.
I have set it up so that my laptop displays on my 2 monitors, but the problem I am having is I can not for the life of me get my laptop display to stop being #1 and have my 2 external monitors not mirror each other.
If you need more information, please let me know!
